1In a large bowl, combine the flour, corn starch, thyme leaves, salt, and black pepper.
Pour the buttermilk into another bowl.
Dip each chicken piece into the buttermilk, ensuring it is fully coated.
Dredge the buttermilk-coated chicken in the flour mixture, pressing the flour onto the chicken to ensure it adheres well.
Heat the vegetable oil in a large skillet or deep fryer to 350°F (175°C).
Carefully place the coated chicken pieces into the hot oil, being careful not to overcrowd the pan.
Fry the chicken for about 10-12 minutes on each side, or until the chicken is golden brown and cooked through.
Remove the chicken from the oil and place it on a paper towel-lined plate to drain excess oil.
Serve hot and enjoy your Southern Buttermilk Fried Chicken!
